Creaming in Class

When I'm sitting in class sometimes I get a boner for no apparent reason. The other day I was in a boring history class and there was a cute girl who I really fancy sitting across the aisle from me. I could feel my dick getting hard in my pants and I started to secretly play with myself. I was very careful and as I was by the classroom wall I turned slightly towards it so I couldn't be seen.

I felt myself slowly getting quite excited. Then I carefully unzipped my jeans and put my hand inside so I could rub my dick through my boxer shorts. I did it very slowly and kept looking at the girls in the class and doing it when they were so close made me even more excited. I rubbed the bulge through the cotton. At first I didn't intend to cum but I was so horny that I just couldn't stop myself and soon all my cream came pouring out into the inside of my boxers. I could feel myself going red and flushing with the excitement but I managed to keep very still till it was over. It felt really hot doing it like that despite the mess I made in my shorts. If only those girls knew what I was doing so near them!

Got to finish this as I'm about to bring myself off as I've read all the stories you guys and gals have written and its got my dick throbbing.
